Embodiment
To describe the structure of discharging refrigerant that is used for linear compressor according to the preferred embodiment of the present invention in detail with reference to accompanying drawing at present.
Fig. 4 to Fig. 6 is side view cutaway drawing and the front elevation that illustrates according to linear compressor of the present invention.
Like Fig. 4 and shown in Figure 5; Be used for the structure of discharging refrigerant of linear compressor; One end of cylinder 2 is fixed to framework 3; Piston 4 insert the other end of cylinders 2 and cylinder 2 in along straight reciprocating motion, emission quotas D1 is formed on an end of cylinder 2, buffer space D2 forms the certain intervals apart with emission quotas D1; The first loop pipe R1 that refrigeration agent flows within it is installed between emission quotas D1 and the buffering space D2, and the second loop pipe R2 that is used to guide the refrigeration agent outside drain is connected to buffer space D2.In emission quotas D1, refrigeration agent flow to the sub-emission quotas 59d with relatively large volume from sub-emission quotas 59a, 59b and the 59c with less relatively volume.Therefore, reduced the pulsation of refrigeration agent.
Emission quotas D1 is limited bleed valve assembly 58 and discharge cover 59, and buffer space D2 is limited framework 3 and buffer cover 60.
At length, an end of cylinder 2 passes framework 3.In an end of cylinder 2, form compression volume P, bleed valve assembly 58 is installed in the outside of the end that will be opened and closed of cylinder 2.
Especially, bleed valve assembly 58 comprises the escape cock 58a that is used to open and close cylinder 2 one ends, is spaced to cover escape cock 58a and to be fixed to the supporting cover 58b of cylinder 2 one ends and to be used for escape cock 58a flexibly is supported on the escape cock spring 58c on the supporting cover 58b.
The part of contact cylinder 2 one ends of escape cock 58a forms flat condition, and the relative part of escape cock 58a projects upwards towards middle body, promptly is convex.Therefore, escape cock 58a can resist the high pressure of compression volume P.Preferably, on escape cock 58a, be formed with the locating slot (not shown), be used to support escape cock spring 58c.
The diameter of the end of the contact escape cock 58a of escape cock spring 58c stably supports escape cock 58a thus less than the diameter of the other end of the contact supporting cover 58b of escape cock spring 58c.The open end of supporting cover 58b is fixed to the framework 3 of the periphery of contiguous cylinder 2 one ends, and the closed end of supporting cover 58b supports escape cock spring 58c.Preferably, a plurality of intercommunicating pore H1, H2 and the H3 periphery that is formed on supporting cover 58b is used for refrigerant emission.
Preferably, three intercommunicating pore H1, H2 and H3 along the periphery that circumferentially is formed on supporting cover 58b at interval 90 degree.Confirm the interior shape of discharge cover 59 according to intercommunicating pore H1, H2 and H3, this will carry out illustrated in detail at the back literary composition.
Therefore, if the pressure in the compression volume P is higher than setting pressure, then escape cock spring 58c is compressed, and the side of escape cock 58a is opened from an end of cylinder 2, and therefore through each intercommunicating pore H1, H2 and H3 high-pressure refrigerant is discharged into discharge cover 59.
In more detail, the first sub-emission quotas 59a, the second sub-emission quotas 59b, the 3rd sub-emission quotas 59c and the 4th sub-emission quotas 59d are formed in the discharge cover 59 to communicate with each other.At this, the first sub-emission quotas 59a, the second sub-emission quotas 59b and the 3rd sub-emission quotas 59c have less relatively volume, and the 4th sub-emission quotas 59d has relatively large volume.The first sub-emission quotas 59a, the second sub-emission quotas 59b, the 3rd sub-emission quotas 59c and the 4th sub-emission quotas 59d along circumferentially being formed in the discharge cover 59 at interval 90 degree.
Preferably, discharge cover 59 covers supporting cover 58b, makes intercommunicating pore H1, H2 and the H3 of supporting cover 58b correspond respectively to the first sub-emission quotas 59a of discharge cover 59, the second sub-emission quotas 59b and the 3rd sub-emission quotas 59c.
To explain an example of the structure that intercommunicating pore H1, H2 and the H3 of supporting cover 58b are corresponding with the first sub-emission quotas 59a, the second sub-emission quotas 59b and the 3rd sub-emission quotas 59c of discharge cover 59 at present.Be assigned to the first sub-emission quotas 59a with less volume, the second sub-emission quotas 59b and the 3rd sub-emission quotas 59c of discharge cover 59 from the high-pressure refrigerant of the intercommunicating pore H1 of supporting cover 58b, H2 and H3 discharging, be pooled to then in the 4th sub-emission quotas 59d with relatively large volume of discharge cover 59.Therefore, reduced the pulsation of refrigeration agent.
Another example of the first sub-emission quotas 59a, the second sub-emission quotas 59b, the 3rd sub-emission quotas 59c and the 4th sub-emission quotas 59d will be described at present.The first sub-emission quotas 59a has minimum volume, and the second sub-emission quotas 59b and the 3rd sub-emission quotas 59c have the big volume than the first sub-emission quotas 59a, and the 4th sub-emission quotas 59d has maximum volume.That is to say that this structure has reduced from the pulsation of the refrigeration agent of the first sub-emission quotas 59a discharging again.As a result, significantly suppressed the pulsation of refrigeration agent.
Except along the intercommunicating pore H1, H2 and the H3 that circumferentially are formed on the supporting cover 58b, can be formed with intercommunicating pore H4 in the central part office of supporting cover 58b.When the refrigeration agent from intercommunicating pore H4 discharging also flow to the 4th sub-emission quotas 59d of discharge cover 59, the pulsation of refrigeration agent reduced.
Preferably, discharge cover 59 is enough big when compression volume P discharges, to reduce the pressure of refrigeration agent at high-pressure refrigerant.But, because buffer cover 60 only reduces from the pulsation of the refrigeration agent of discharge cover 59 transmission, so the volume of buffer cover 60 can be set at the volume less than discharge cover 59.
Though discharge cover 59 is fixedly mounted on the framework 3 with buffer cover 60, because surface of framework 3 and non-flat forms, so discharge cover 59 is not provided with at grade with buffer cover 60.
The first loop pipe R1 and the second loop pipe R2 are the pipes that has than minor diameter.The first relatively short loop pipe R1 is installed between discharge cover 59 and the buffer cover 60, is used to guide flowing of refrigeration agent.The relative second long loop pipe R2 is installed between buffer cover 60 and the space outerpace to guide the noise that pulsation was produced of the mobile of refrigeration agent and reduction refrigeration agent.
The first loop pipe R1 is communicated with the 4th sub-emission quotas 59d of discharge cover 59, makes that the refrigeration agent in the 4th sub-emission quotas 59d that collects in discharge cover 59 can be discharged into buffer cover 60.
For the situation of the first loop pipe R1, can tubule be mounted to rectilinear form.For the situation of the second loop pipe R2, vibration and the noise of canal curvature ground installation that preferably will be not only thin but also long to reduce refrigeration agent effectively.Reduce to minimum for the vibration and the noise that make refrigeration agent, consider the vibration frequency of refrigeration agent, can the buffer component (not shown) such as rubber be installed in the part of the second loop pipe R2.
Especially, in order to cushion the pulsation of the refrigeration agent in the buffer cover 60, the end of the end of the first loop pipe R1 and the second loop pipe R2 preferably is arranged in opposite direction in the buffer cover 60 so that its apart from each other each other.More preferably; The end of the first loop pipe R1 is arranged on an end of buffer cover 60 dearly; And the end of the second loop pipe R2 is connected to the other end of separator tube 60; Make the high-pressure refrigerant that is fed to buffer cover 60 through the first loop pipe R1 in buffer cover 60, to be cushioned, and discharge along the second loop pipe R2.
Process according to discharging refrigerant row in the structure of discharging refrigerant that is used for linear compressor of the present invention will be described at present.
When piston 4 in cylinder 2 during along straight reciprocating motion, if the pressure in the compression volume P is lower than setting pressure, the slim suction valve 6 that then is installed in piston 4 one ends is opened, and makes refrigeration agent can pass the ostium 4h of piston 4 and flows in the compression volume P.Pressure in the compression volume P raises, and under suction valve 6 and escape cock 58a closing state, refrigeration agent is compressed.If the pressure in the compression volume P is higher than setting pressure, then escape cock spring 58c is compressed, and makes the side sections of escape cock 58a open an end of cylinder 2.
When the side of escape cock 58a was opened, high-pressure refrigerant discharged from compression volume P, and was transferred to discharge cover 59 through intercommunicating pore H1, H2, H3 and the H4 of supporting cover 58b.When the volume of high-pressure refrigerant increased in discharge cover 59, the pressure of high-pressure refrigerant can partly reduce.
Because piston 4 along to-and-fro motion linear continuously, so high-pressure refrigerant is discharged into discharge cover 59 from compression volume P, produces pulsation in cylinder 2.But; When refrigeration agent from the first sub-emission quotas 59a with less relatively volume, the second sub-emission quotas 59b and the 3rd sub-emission quotas 59c of discharge cover 59 flow to discharge cover 59 have the 4th sub-emission quotas 59d of relatively large volume the time, the pulsation of refrigeration agent is partly reduced.
Reduce in discharge cover 59 from the pulsation of the refrigeration agent of compression volume P discharging.Refrigeration agent discharges from discharge cover 59, and is fed to buffer cover 60 through the first loop pipe R1.
The end of the first loop pipe R1 is arranged in the buffer cover 60 dearly, and the edge, end of the second loop pipe R2 direction opposite with the end of the first loop pipe R1 is arranged in the buffer cover 60.When refrigeration agent when the first loop pipe R1 is transferred to the buffer cover 60 with relatively large volume, the pulsation of refrigeration agent obtains buffering.Afterwards, refrigeration agent flows into the second loop pipe R2.
When refrigeration agent flow through the second relatively thin and long loop pipe R2, the pressure of refrigeration agent, vibration and noise reduced simultaneously.The buffer component that is installed on the second loop pipe R2 has improved the effect that reduces refrigeration agent vibration and noise.
Because piston 4 in cylinder 2 repeatedly along straight reciprocating motion, so high-pressure refrigerant discharges through discharge cover 59, the first loop pipe R1, buffer cover 60 and the second loop pipe R2 continuously.
Though described preferred implementation of the present invention, be appreciated that the present invention should not be limited to these preferred implementations, but those skilled in the art can carry out various changes and modification in the desired the spirit and scope of the present invention like claim.
